BARREL-HOOP MACHINE.

SPECIFICATION forming part of Letters Patent No. 243,292, dated June 21,1881. Application filed April 20, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES NAYLOR, Jr., a citizen of the United States,residing at Rochester, in the county of Monroe and State of NewYork,have invented certain new and useful Improvements in Barrel-HoopMachines;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention,such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to theletters or figures of referencemarked thereon, which form a part of this specification.

My invention relates to a machine for the combined purpose of dressingand rendering wooden barrel-hoop blanks; and it consists in thecombination and arrangement of parts in such a manner that taperedhoop-blanks of any width are dressed or the corners rounded ofl by theoperation of the machine.

The object'o'f this improvement is, first, to construct a machinecapable of dressing any width of hoop-blank; second, to allow the blanksto be fed straight through the machine; third, to hold the blankaccurately to the action of the cutters; fourth, to prevent clogging ofshavings and to relieveit from broken pieces, which often get wedged in;fifth, to render or limber the dressed blanks, as will be hereinafterdescribed.

In the drawings, Figure l is a side elevation Fig. 2, a front elevation;Fig. 3, a plan of table, lower rollers, and their shafts Fig. 4, a Viewof the dumping arrangement of table, and Fig. 5 a detailed view, showingsection of dressed hoop-blank, cutter, and table.

A A represent the frame of the machine. Power is communicated from acounter-shaft located overhead by the belts B B. The cutter-head isdriven by the belt B independently, the belt B driving the feed-pulleyc, secured to the'shaft D, on which is the pinion E, engaging with bothspur-gears F F, secured to the lower roller-shafts, G G. The upperrollers, on account of their large diameter, do not necessarily requireto be geared.

H H are smooth unyielding feed-rollers, being of larger diameter thanheretofore, so as to feed more effectually. H H are smoothunyieldingfeed and pressure rollers, and are made larger than theothers, H H, so as to strain the hoop-blanks in passing through themachine. All these rollers are run in positive or rigid bearings, therear ones being arranged out of 5 square with a line of the passage ofthe hoopblanks, as shown in Fig. 3, the dotted lineww being at rightangles to the line of passage of the blanks. This, together with theshoulders h h h h h it, constitutes the means by which bended and narrowhoop-blanks are kept to an exact position when acted upon by the cuttersP. By this arrangement hoop-blanks of all widths can be dressed, asthere are no confined guides for the blanks to pass through. The lowerrollers are provided with angular recesses coinciding with the table, asshow-n in Fig. 3. The upper ones are straight, as shown in Fig.

2. A most important purpose which they perform is to render or limberthe blanks,so that breakage in coiling is prevented. Immense pressure isbrought to bear by forcing, or rather feeding, a blank three-eighths ofan inch in thickness through an opening only a quarter of an inch. Bythis effective arrangement the wet hoop-blanks are nearly dried and thenature of the woody fiber entirely changed, possessin g better qualitiesforits purpose. Barrelhoops so made are stronger, and can be coiledwithout resteaming or boiling. Although the blanks are compressed in theoperation, the

compression given by the rollers does not remain, but, on the contrary,it assumes its shape given by the action of the cutters. Thesehoop-blanks, when operated upon, are always steaming hot and saturatedhence these various devices are to serve the condition of the same. Incutting the blanks there is more or less variation, and to provide forthis the front rollers are set to meet the thinnest blank. Consequentlythe thicker ones are more or less compressed, as the openings betweenthe rollers are always the same. Thus the pressure exerted to feed theblanks is given by the blanks in contradistinction'to weights or springs which 9 5 have heretofore been used.

I is the table, provided with 'twoor more angular recesses, whichcoincide to the taper of the hoop-blank. Thus the shoulders h h h areformed, which serve as guides for the ion blanks, and against which therollers H H, being out of square, are constantly forcing the same. Thistable is so made as to be quickly dumped. I prefer to hinge it andsupport it on the outer edge, as shown in Fig. 4:. This is for thepurpose of relieving the machine of broken pieces, which often getwedged in be tween the table and press-bars. In Fig.1 the table is shownin place; in Fig. 4, dumped, so as to allow the pieces to fall out. Assoon as the support is taken away it falls by its own gravity. Inmachines without this device a stoppage of all parts is absolutelynecessary, together with a loosening of parts; but now in and by the useof this improvement it is done in an instant, without any stoppagewhatever of the working parts.

The casting or piece N, to which the table is hinged, has also thepress-bars 0 0, solid or socured firmly to it, the whole beingvertically adjustable to the cutter-head P, which has secured to itcutters which conform in shape to the outside of a barrel-hoop, as shownfull size in Fig. 5. These cutter-heads revolve rapidly in rigid bearings and dress orshape theblanks -ings, slivers, and broken pieces, whichif j on the outside as fed through the machine.

accomplished by means of the set-screw Q.

when the press-bars are adjusted to the cutters the table is alsoadjusted by the same means, the blanks being always of the same:

thickness.

the constant clogging of the parts with shavwet make it still worse. Inthe present case devices are used and the various parts are so arrangedthat there is no chance for dross to accumulate, or should it happen todo so it passes out freely before it causes any annoyance.

In advance of the front feed-rollers are the openings for feeding in theblanks. These openings are made as large as possible, the limit being sothat two blanks cannot enter together. Attached to the frame is thelower piece, J, as shown in Fig. 1, and secured adjustably to it is theupper piece, K. Each of these pieces have angular recesses, one reverseof the other, so that when put together the oblong openings are theresult, and by moving the upper piece, K, in or out said openings aremade of, any required width. To feed the blanks rapidly and always havethe same enter the openings, the shields L are so arranged of differentsizes as to guide the blanks exactly to the openings.

The operation of the machine is as follows:

Hoop-blanks are fed to the machine by being presented laterally to theshields L, which, being of different sizes, the smallest outside andtending inwardly direct to the openings, enable the operator to feedeasily as well as rapidly. The blanks are caught by the frontfeed-rollers, H H, which tend to throw them out in front and in beyond,as shown by the arrow in Fig. 3. This is caused by different diametersbearing on the surface of the blank. As it passes along it comes inbearing contact with the shoulders h h h of the table,'which, togetherwith the table I and press-bars 0 0, hold the blank in exact positionwhile being acted upon by the cutters. It then is caught by the rearfeed and pressure rollers 11' H, which, being larger in diameter, pullor strain on it to keepit tight between the rollers. These rollers H Halso squeeze the fibers together, so that in coiling they lay morereadily together, and hence do not break. The tendency of these rearrollers is exactly the same as the front ones. This being wrong, it iscounteracted by placing the shaft outof square, as be- A pivoted arm, M,is attached to the cast-. ing or support N in such a manner as tosupport the table I when said arm is in a vertical fore described, andby this means the dressed blanks come square out of the machine.
